TAPE CUTTING ATTACHMENT FOR 'SPOOLS Filed Feb. 28, 1945 1. MN m m lllllllllllllllll 4 Inventor ori-lea 2 Claims. (61242-555) similar material. and the invention has for its primary object to provide a cutter carried by the spools for cutting the tape.

An important object of the present invention is to provide a cutter of this character adapted for movement around the inside of the flanges of the spool so that the cutter may be positioned at a desired point in the spool for cutting the tape at a desired length.

A further object of the invention is to provide means for pivotally mounting the cutter in the spool, together with finger-gripping means for firmly holding the cutter against the tape while the latter is being cut.

A still further important object of the invention is to provide means to prevent the move A still further object is to provide a device of this character of simple and practical construction, which is emcient and reliable in operation, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantagesreside in the details of construction and operation as mo'refully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like reference numerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view of the spooi,

Figure 2 is a sectional view taken substantially on a line 2-2 of Figure 1,

Figure 3 is a transverse sectional view taken for the purpose of illustration, I have disclosed a preferred embodiment of the invention, the numeral 5 designates a spool generally of a type .adapted for containing adhesive tape or similar material 6 rolled on a huh I supported between the flanges 8 of the spool.

The opposed surfaces of the flanges 8 are formed with annular grooves 9 within which runners I II are slidably mounted for movement circumferentially at the inside of the spool in the grooves 8. the runners being connected by a pin ll extending transversely of the spool. and on which a blade I! is pivotally mounted by means of bearings II formedat the rear edge of the blade.

The front edge of the blade is beveled, as indicated at ll. to provide a sharp cutting edge adapted to bear against the periphery of the rolled tape in amanner as indicated in Figure 3 of the drawing.

Also pivoted on the'pin H is a finger-gripping tongue I! projecting rearwardly from the pivoted end of the blade I! and providing finger-gripping. means for pivotally actuating the blade to swing the cutting edge thereof into and out of engagement with the tape. and to exert a desired pressure on the cutting edge of the blade to hold the same firmly against the tape while sections of the tape are cut at the sharpened edge It thereof.

The runners Ill areprovided with inwardly projecting stops I8 overlying the blade l2 to limit outward swinging movement thereof beyond the peripheral edges of the flanges 8 and thus prevent proiecting of the sharpened edge of the blade outwardly beyond the edges of the spool to avoid injury to persons while handling the spool. Y

The tongue 15 is formed at its inner end with a stop lug ll adapted to bear against one side of the blade l2. as shown in Figure 3, when the tongue is raised to force the blade downwardly against the tape and thus firmly hold the tape while the latter is being cut. The tongue 15 may normally swing downwardly into a position between the fianges of the spool. as shown in Figure 4, when not in use. A stop lug I8 is also formed on the bottom of the tongue IE to bear against the other side of the blade l2 and limit downward movement of the tongue. By depressing the ton ue IS with the stop lug i8 bearing against said other side of the blade It, said blade may be swung to disenga e the same from the tape 6, when desired.

In view of the foregoing description taken in conjunction with the accompanying drawings. it is believed that a clear understanding of the construction. operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however. that even though I have herein shown and described a preferred embodiment of my invention that the same is susceptible to certain changes fully comprehendedby the spirit of the invention as herein described and the scope of the appended claims.

Baving thus described the invention, what I claim is: a

1. A tape cutter for tape epoch and comprising a blade positioned between the flanges oi the spool, said flanges having annular grooves in their opposed iaoes. runners adapted to travel in the grooves, a hinge pin connected to the runners. a blade pivoted at one edge on said pin, and a finger grip pivoted on the pin and having means thereon for engaging opposite sides 0! the blade to' raise and lower the other edge thereof upon pivotal movement of said grip.

2. .A tape cutter for tape spools and comprising a blade positioned between the flanges oi the spool. said flanges having annular grooves in their opposed faces. runners adapted to travel in the grooves. a hinge pin connected to the runners, a blade pivoted at one edge on said pin. means for manually raising and lowering the other edge of the blade. and a stop carried by one of the runners engageabie by the blade to limit its raising movement.
